Application led April l, 1910. Serial No. 652,981.

To all whom, t'may concern Be it known that I, Trronas P. Wauu, a citizen ofthe United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Axminster Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In weaving moquette or Axminster cirpets, great expense in machinery, labor, floor space, and time is caused by the requirement of the so-called Axminster spools and their tube frames for providing the pattern yarns or. pile tuft yarns for the carpet,

and accordingly my invention has for its object the saving of this expense by eliminating said spools', tube frames, and all the attendant mechanism. Also an Axminster carpet has heretofore required tivo shots or a double thread of filling "for each weft weaving movement, because Axminster looms, as heretofore made, have necessitated the employment of a fillingthread needle for car ing the filling thread through the shed to engaged and locked at the adjacent selvage by a selvage thread delivered by a small shuttle moving longitudinally of the warps at that edge lof the fabric, the needle being then retracted to permit the beating-up movement; and it is one object of my invention to provide the loom with a filling shuttle movement for accomplishing the bmdin of the piles instead of the Said needle andv selvage shuttle, whereby, not only are the piles bound in place by a. shuttle movement, but also an Axminster carpet no longer need require two binder threads for each weft movement, but can be made with one binder thread if desired, besides F or example, the selvage has heretofore been necessarily defective because of the irregularity in position and tension due to the needle and selvage shuttle movements, one selvage being made with the aid of said selvage shuttle and the other without it, whereas the provision of a binder shuttle movement insures a perfect and uniform selvage'at both edges of the fabric. Also, I have succeeded in devising an Axminster loom employing a heddle movement,

preferably a drop-shed jacquard, whereby the pattern yarns or tuft yarns are sure to be inserted in 'the carpet atvexactly their right position or location, whereas one difficulty commonly experienced in connection with thc use of tube frameshas been the improper placing, at times, or entire omission of some of the pattern yarns or tuft yarns from their proper places in the carpet. I regard as the principal advantage of my invention 'theprovision of means rendering it possible to weave the Axminster piles directly from one and thesame continuous source or main supply o f pattern yarnsor tuft yarns, The practical advantages resulting therefrom are many: For example, the supply may thereby be practically unlimited, as distinguished from the necessarily limited quantity of pattern yarns carried by the individual spools, the tension on the individual yarns may be maintained uniform at all times, heretofore lconsidered impossible. in connection with Axminstervspoolava great saving of pattern varns is made, the length of fabric or numr of picks required is not dependent in any wai; upon the number of spools for which t e spool-carrying chain is made up (which has heretofore largely influenced the manufacturer as to the' number of picks in a rug), but I provide for the same unre stricted freedom of Weaving as in any 'ordinary loom, practically all the yarn handling and manipulating operations take place directly in the loom itself and take place automatically, as distinguished from requiring a large portion of said yarn handling and manipulating to be done in connection with spools and tubes before reaching the loom` or in other Words, m invention provides practically all the faci ity of yarn handling and loom movements afforded b \Vilton and Brussels looms, together wit the advantages of the Axminster loom as to cutting off the individual rows -of piles one by one as they are woven, my invention effecting the saving of yarn due to the Axminster weave over the waste of yarn in burying it in the Wilton and Brussels weave, and yet providing the facility and desirable features of yarn-handling and weave movements of the latter.

In the accompanying drawin I have shown a preferred embodiment o my invention, which is further explained in the fol- In the drawings, Figure 1 is a central vertical longitudinal sectional view of the loom; Fig. 2 is a top plan view thereof; Fig. 3 is a fragmentary front elevation; Fig. 4 is a view in front elevation of the strippers; Fig. 5 is an enlarged sectional detail similar to Fig. 1, for more clearly showing one step in the weaving operation; Figs. 6, 7, 8, and 9 are fragmentary sectional viewsV similar to Fig. 5 showing successive steps in the weaving operation; Fig. 10 is a diagrammatic view showing my improved Axminster weave; Fig. 11 is a similar diagrammatic view showing the usual Axminster weave, wherethe filling is put in by a. needle; and Figs. 12 and 13 are cross sectional views on the lines 12-12 and 13-13, Fig. 2, showing certain of the cams.

As already intimated, my invention is broadly new in providing means for weaving an Axminster carpet or rug without requiring Axminster spools and yarn-de livering tubes and tube frames, and needles with the attendant uncertainty of their loose-end attern yarns, so that it will be understood) that, in describing the details of the loom of the drawings, said mechanism constitutes a preferred embodiment only, the invention being capable of a wide variety of embodiments without de arting from the broad-nature and sco o the invention.

In a suitable loom rame 1, I mount a cam shaft 2, breast beam 3, take-up'roll 4, press roll 5, lay sword 6, lay beam 7, reed 8, binderwarp beam 9 for delivering the binder warp threads 10, 12 over a whip roll or back roll 13, stutfer warp threads 14 being de livered over an adjacent whip roll or back roll 15, harness'frames or shedding mechanism 16, 17 for the binder warp threads, a harness frame 18 for the stu'er warp threads, and a shuttle 19 for delivering filler thread. All the aforesaid parts ma be operated by any usual mechanisms, which, being common, are -not herein shown in further detail. Adjacent the fell, herein shown as just above the same, I provide yarn-holding means, herein shown as preferably consisting of a stationary rail or yarn holder 20 of suitable sha e and having on its under side a suitable riction surface of leather, felt, or the like, extending across the loom from the inner ends 21 of arms 22 secured to brackets 23 slotted at 24 to afford \ertical adjustment for said yarn holder. Normally coperating with the yarn holder 20 is a second yarn holder, herein shown as composed of `two -transverse members 25, 26 provided with interlocking ends at their meeting point 27. see Fig; 2, said two mem? bers 25, 26 of this coperating yarn holder being carried respectively by the lower up turned ends of arms 28, 29. These arms 28, 29 are mounted on a rock shaft 30 andpreferably have two movements, as herein shown,

A two levers 67, 68 4 -two movements as t e levers 28, 29 by means 4tially the same in a spline 31 permitting them to slide longitudinally on said shaft at desired intervals while compelling them to rock with it. The rock shaft 30 is actuated by a crank arm 32 connected by a link 33 with a cam lever 34 pivoted at 35 to the frame of the machine Aand provided with a cam roll 36 actuated by a path cam 37 on the shaft 2. The lateral or sliding movement of the arms 28, 29 is given by a cam 38 in whose path travels a cam roll 39 of a lever 40 pivoted at 41 on a stand 42 and connected bya link 43 to a crank pin 44 adjustably secured at 45 in-an arm 46 of a toothed sector or gear 47 which engages a pinion 48 whose shaft 49 carries at its upper end a sprocket wheel 50 .engaged by a sprocket chain 51 which extends across f the loom and around a s rocket idler 52 at the opposite end of the rame, said chain at its rear portion being secured at 53 to a lug 54 projecting rearwardly from the upper end of tlm arm 28 and at its front ortion at 55 to a similar lug 56 projectingI orwardly from the upper end of the arm 29. The front portion of the chain passes through openings 57 in the arms 28 and 29 to permit of the rocking movement of the levers with relation to the chain and of the longitudinal travel of the chain with relation to the levers.

The rock shaft 30 is journaled in U- shaped hangers or brackets 58, and thev sprocket wheels and adjacent parts are su ported in standsor brackets 59. Below t e shaft 30, I preferably provide a similar rock shaft 60 actuated by a crank 61, link 62, cam lever 63 pivoted at 64 and having its cam roll 65 actuated by a ath cam 66.0n the shaft 2. On this rock s aft 60 are -mounted rovided with the same of sprocket wheels 69, a shaft 70, pinion 71, toothed ,sector or gear 72, adjustable crank pin 73, link 74, lever 75` pivoted at 76, having its roll 77 actuated by a path cam 78, and a. sprocket chain 79 secured to the respective levers 67, 68 at 80, 81, all substaneneral construction and operation as alrea y described for the two levers 28, 29. The swinging levers 67, 68 operate a stripper or pattern-yarn separating mechanism, herein shown, fory convenience of illustration, as consisting of two finger-like members82, 83 whose ends are shaped to interlock or overlap as indicated at 84, Fig. 2. The pattern yarns or colored yarns from which the pile tufts are to be formed are indicated at 85,v being delivered fromY any suitable source of supply as a i are delivered to any suitable pattern controlling mechanism, a dro shed jacquard mechanism being much pre erred because of its capacity to coperate to the best advantage with the referred mechanisms thus far described. he color yarns pass through the eyes of heddles 86 provided with lingoes 87 at their lower ends and lifting wires 88 at their uppr ends, governed by indicator wires 89 he inoperative by s rings 90 and governed by a usual card cy inder 91 and pattern card chain 92, this being one well known t 'pe of pattern controlling'mechanism, alt ough I do not intend my invention to be restricted to any kind of yarn seleetive means. The wires 88 have hooks 93 at their upper ends adapted to be normally enga ed with stationary bars or grifs 94 and li ed b v lifter bars or knives 95 in well known manner. 0n the respective heddle cords I provide positioning knots 96, herein shown as successively higher from the front toward,

the rear to correspond with the heddle eyes, this provision being for the purpose of positively stop ing the selected yarns at a predetermine position b their engagement with the comber boar 97 to revent the heddles from accidentally with rawing the forward or tuft end of the selected yarns from weaving position, as will presently be more flly explained. At the fell of the fabric being woven, I provide tuft-shearing mechanism, herein shown as comprising a shear 98 and a cooperating shear 99, the former for convenience being made in two )arts integrally with the yarnholding memhers 25, 26, but as the front edge or portion of said integral parts performs an entirely separate function from the rear edge or portion, the said integral parts virtually constitute two distinct mechanisms, and I intend it to be understood as such irres tive of whether the mechanisms are entire y separate from each other or formed integral y as single ieces. The members 98 are carried bv t e arms 28, 29, and accordingly have the movements which have been a1- ready described for the yarn-holdin members 25, 26. The shear 99 prefer-ab y consists of a single shear-plate extending across the, machine and supported at its opposite ends by slides 100 traveling in ways 101 in the normally stationary arms 22, said blade 99 being reciprocated in said ways 101 b levers 102 at the opposite ends of a roc shaft 103, said levers having slots 104 in their upper ends for receiving pins 105 projecting from ears 106 de nding from the under side of the shear ife or plate 99. The rock shaft 103 is actuated by a crank or lever 107 connected by a link 108 to a cam lever 109 pivoted at 110 and having its cam roll 111 actuated by a path cam 112 on the shaft 2.

In operation, let it be supposed that the parts are in the position shown in Figs. 1 and 5, the free ends or forward tuft ends of all the colored or pattern yarns being held gripped between the coperating yarn holders 20 and 25, 26, and the stripper mechanism 82, 83 being above the shed and between the unselected pattern yarns indicated at 85 and the selected pattern arns 113. The actuating parts are so time that `the stri per mechanism 82, 83 is first swung forwar by its arm 67, 68, during which movement the shear 99 is moving forward out of the way to the position/ shown in Fig. 6, and as the stripper mechanism 82, 83 gets almost to the yarn holders and practically over the fell, the lower yarn holder mechanism 25, 26 retreats Vforward just ahead of the forwardly moving stripper 82, 83, thereby arriving at the plosition shown in Fig. 6 and permitting t e stripper to take its place in holding relation to the yarns as shown in Fig. 6. The stripper, however, instead of holding all the pattern yarns between it and the holder 20, now holds the unselected pattern yarns on its upper side and the selected pattern yarns 113 below it at the fell the vlatter yarns being pinched by said stri per 82, 88 against the fabric which is held) taut by the takeup and warp beam. During this forward movement of the stripper mechanism, and preferabl just at the rlibofinning thereof the shutt e 19 has delive a strand 14 of filling in the shed formed by the inde warps 10, 12, and the reed S follows the forward movement of the stri per mechanism, thereby beating up the lling 1 14 to ythe fell as the stripper mechanism reaches 'time the selected pattern yarns 113 are being lifted throu the shed from their lowered position, ig. 5, to their lifted posi' tion, Fig. 6. As soon as the selected pattern yarns 113 have been moved to their upper position, a second pick 115 of binder thread is shot across through the shed by the shuttle 19 4and is immediately beaten up by the reed 8, and then followed if desired by another pick 116 of binder thread, which in turn is immediately beaten up by the reed, the stuer warp thread 14 being moved by its harness 18 pr rly to cause these binder threads 114, 115, 116 to be laid as shown in Fig. 10 with relation to said stuer thread. In Figs. 5-9 I have omitted the1 stuter thread to prevent confusion in the drawing. While the binder thread is being shot back and forth by the shuttle 19, the arms 28, 29 are being slid away from each other on their rock shaft 30 until they are in position to swing by the adjacent arms 67, 68, whereupon the rock shaft 30 is turned so as to swing said arms 28, 29 rearward to bring the yam-holding members 25, 26 to the rear of the stripper mechanism and above the warp threads, and under the selected and now lifted pattern yarns or tuft yarns 113. Thereupon the arms 28, 29 are slid toward each other on their rock shaft 30 until the yarn-holding members 25, 26 meet beneath the selected pattern yarns 113 in the position shown in Fig. 7. The arms 28, 29 and the yarn holders 25, 26 and shear members 98 carried thereby are then moved forward to the position shown in Fig. 8, and just as the shear members 98 have gotten practically over the fell, the stripper members 82, 83 moved forward out of the way and then stop or open out laterally of the loom so as to get out of the way of the shear member 99 which moves to meet the shear mechanism 98, which meanwhile has raised and bent forward the pattern yarns 113, which are now sheared oli' by the cooperating cutting edges of the members 98 and 99, leaving a row of sheared piles as shown in Fig. 9 beneath the members 25, 26 and leaving all the pattern yarns held clamped above said members 25, 26 against the yarn holder 20. During the completion of the shearing movement, the arms 67, 68 and stripper members 82, 83 are swung rearwardly and inwardly to their original position, as shown in Figs. 5 and 9, and the knife or shear 99 then moves back. In Fig. 11, I have indicated at 117, 118, 119the binder threads as heretofore necessarily laid in pairs by the usual needle employed in Axminster looms. and one advantage of my mechanism will be seen by comparing said Fig. 11 with Fig. 10, where only one binder thread, instead of a air, is employed each time, this being ren ered possible by providing an Axminster weaving mechanism capable of employing a shuttle instead of a needle, one advantage of havin a single binder thread instead of a pair ieing that thereby a uniform andpractically perfect selvage is obtained at both edges of the fabric. Also the weaving proceeds at a faster speed, and this feature also coperates with the selecting mechanism in producing a finer weave. The selecting mechanism permits a much finer weave transversely of the fabric than the Axminster spool and tube mechanism, while the shuttle binder thread mechanism permits a finer weaveA longitudinally of the fabric. My Axminster weavin mechanism permits a practically unlimite range of colors, not being limited in this respect to the narrow range or variety of pattern yarns made necessary in needle tuft-weaving looms. Tube and spool Axminster weaving is able to produce a finer weave and a larger range of color effects than needle tuft-weaving, and my mechanism improves the product in both of these respects, i. e. it is capable of weaving finer and with a wider range or number of color yarns than the tube and spool Axminster mechanism.
